IMPROVEMENT, IN COMBINED THIRESEING'M.A.C2HI1\`I'E AND SEPARATOR.

The Schedule referred to in these-Letters Patent and making part of thesame.

` art to make and use `the same, reference being had to theaccompanyingr drawing, forming part of this specication. g

rlhis invention relates to` new and useful improvements in machines forthreshing and cleaning grain, whereby many ofthe objections to the oldstyle of threshing-machines are obviated; and f It consists iu thepeculiar construction of the lseparator, or the portion which 4separatesthe `grain from the straw, but is not.` confined thereto, but embracesthe construction, arrangement, and combination of parts, as Will' behereinafter nnorefully described.

In the accompanying sheet of drawings- `Figure 1. represents averticallongitudinal section. of the machine through the line x x of tig.i 2

Figure 2 is a top or plan view. 4 Figure 3 is a detached view of therear end of the fanuing-mill.

Similar lletters ,of reference indicate corresponding parts. U Arepresents the threshing portion of the machine, which does not differmaterially from those of ordinary construction.` y

t Bis the separating portion, and

O is the'fanning-mill for winnowing the grain. The grain to be threshedis passed ythrough the threshingmachine A, and the straw, chaii', and

. grain are delivered therefrom on to they separating- This `door isenclosed by side-boards E, and consists of two layers or aprons, oneVabovethe other, the upper one, F, being perforated with numerous holesfor allowing the grainl and chad' to pass through on to the apronbeneath.

The lower. apron rated, angular transverse channels being formedthereon,ras,represented in iig. l.

` The upper apron vllhas two (more or less) serrated strips, H, attachedto its upper side, as represented.

The perforated apron F', with the strips H and the serrated apron G, areunited together and receive a longitudinal motion` from the crank I, bymeans of the connecting-.rod J, which is attached to the under side ofG, as represented in the drawing.

G is tight, b'ut corrugated or ser-` The rapid longitudinalshaking-motion imparted to the floorD serves to separate the grainfronrthe straw while the motion is such that the straw is carried up bymeans of the teeth or angles of the serrated strips H, and the grain andthe chann are'carried up onthe serrated apron G beneath. l The former iscarried over from the separating-floor Dpand delivered on to'the apron Kin front of the mill.

1t will be noticedthat the apron G (or lower portion oftheseparating-Hoor D) is shorter than the upper portion, so that the grainand the chai combined with it, is delivered into the hopper L of thefanning-mill, from which it passes on to the s'ieves and screens of 4themill, and the ch'ai` being blown ott and the grain cleaned, the grain isdelivered at the rear end of the mill, in the usual manner. l

As the relativeweight varies materially in different kinds of grain, andthose of the same kind in different seasons and of different sowings inthe same season, the amount of blast in the separator must be graduatedcorrespondingly.

The shaft which rotates the wings of the fan is op-v erated hy a beltconnected with the mechanism of the threshers, whose requirements mustgovern the amount of powerapplied to the machinery. r It becomesnecessary,'then, to possess some other means of regulating the blast.the ordinary'driving-power `as amaximum, and graduatigdownward by meansof adjustable.apertures,I which'will waste and lessen the blast indifferent-degrees. For instance, with tine plump -wheat weighing sixtypounds to the bushel, the slide is closed entirely and the full force ofthe blast allowed to play upon the grain, chan, and straw that haspassed through the thresher; kbut when I have rusted wheat, or adilerent kind of grain, which weighs only ifty pounds to the bushel, Iopen the sliding door, so as f to disclose a' sufficient opening towaste and decrease the force of the blast.

The arrangement is. plainly seen in g. 3, where 'n represents theair-criticos, o the adjustable slide, and p the opening, for thedischarge ofthe cleaned grain.

The separator B andthe mill Q are connected permanently together, butthe separator is connected with the thresher `by hooks and staples, sothat it can be readily detached therefrom, for transportation, storage,or for other purposes.

The separating-floor D restson cross-bars, the ends `of which are seenat r, tig. 1. l

These bars are suspended byfrods, atcach of their ends, from ktheoutside of the side-boardsg, so that the floor, or aprons F G, do notslide,"'but. swingn This I accomplish by takin-g s ivhieh allows them toreceivev the required jenking- 2.
